This is a parametric openscad design for a flat 'fresnel'-type mirror for concentrating sunlight, made out of lasercut parts and flat mirrors. It is a work in progress that i decided to upload early, please note: The preview does not work for settings of xSize and ySize > 2. Rendering works fine. Non-square matrices are rendered faulty. Oops. Read the comments in the code for some explanation on how to use All the resulting x- and y parts for mounting the mirrors are the same. It should be possible to greatly simplify this design.. Do not unerestimate the neccessary rigidity and accuracy for an optimal focal point. The DXF files were used for the 5x5 mirror cut out of 4mm MDF on the photo and in the preview. The focal point is to a side, 500 mm in front of the frame. Please be careful with larger mirrors in the sun ! Print Settings Printer: Lasersaur Post-Printing The frame was glued using wood glue. The mirrors are cut and glued with hot melt glue. To improve alignment the thing was heated up in an oven to soften the glue and the mirrors pressed into their sockets.
